Spiders are well known for their web architecture and potential as bio-control agents. A web building spider relies on its web to capture prey for its sustenance. In this paper we described the web structure of Neoscona vigilans and its efficiency of prey capture. Observations were made on different web variables namely, spider orientation, web symmetry, spider size, web morphometry, mesh width and size of prey captured in the web. Significant correlations were obtained for different body sizes of spiders and web diameter, spider size and height of web for this species. Whereas there was strong negative correlation between mesh width and size of prey captured in the web. We conclude from these co-relative studies that for efficient prey capture N. vigilans construct webs at different heights and of different sizes but always maintain the basic web structure, where the role of mesh width depends on the biology of prey.
